OT-1 Genotyping Results. OT-1 genotyping results demonstrate the 238 bp OT-1 fragment was amplified from OT-1 positive transgenic mice (lanes 2, 3, and 5) but not from negative littermates (lanes 1, 4, and 6). Plasmid pcRTOPO2.1 containing the cloned OT-1 product was used as a positive control (lane 7).
